Methods of Vegetative Propagation:

Natural Vegetative Propagation

PROPAGULES 

DESCRIPTION

EXAMPLES

Rhizome

 

  • Underground, horizontal, branching stem.

Ginger, turmeric etc.

Stem tuber

 

  • Swollen tip of underground, lateral stem.

Potato, artichoke etc.

Corm

 

  • Short, vertical, underground stem, swollen with reserved food.

Crocus, gladiolus etc.

 

Bulb

 

 

  • Underground, lateral branches.
  • Their ends turn up and produce buds.

Mint, pear, banana etc.

Runners

 

  • Grow rapidly along the ground, producing buds and adventitious roots at intervals. These become separate plants.

Strawberry, creeping grass, Desmodium etc.

Offsets

 

  • Short stout runners terminated by a single bud.

Houseleek (Pistia), Eichhornia etc.

Stolon

 

  • When a weak stem falls over and touches the ground, its tip swells. It develops adventitious roots and the further growth is continued by a lateral bud.

Blackberry, fern etc.

 

Root tubers

 

  • Swollen fibrous roots, each capable of developing into a new plant.

Dahlia, sweet potato etc.

 

Leaf buds

  • Bud detaches and grows into a new plant.

Dahlia, sweet potato etc.

Bulbils

  • Detachable buds

Yam etc.


Artificial Vegetative Propagation

METHOD

EXAMPLES

Cutting is removing a portion of the stem and fixing it into the soil to allow the growth of roots and shoots.

 

Stem cutting: Rose, Bougainvillea, etc.

Root cutting: Lemon, tamarind etc.

Grafting is joining a part (stem or bud) of a living plant to another, causing it to grow as a part of another plant.

Types of grafting

Approach grafting

Cleft grafting

Tongue grafting/whip grafting

Bud grafting

 

Sapota, mango, guava, apple, orange, peach, rose etc.

Layering is a method in which a branch of the plant is covered with some material and supplied with water to produce roots.

Types of layering

Air/aerial layering

Ground/mound layering

 

Hibiscus, jasmine, rose, Bougainvillea etc.
